The outer edge of the circular plate 6.2 is fixedly connected to the inner circumferential wall of the cylindrical housing 6.1 via a connecting plate 6.2.1, thereby supporting the bottom of the annular housing 6.1. The inner circumferential wall of the annular housing 6.3 is provided with a plurality of water inlet holes 6.3.1, allowing water from the top end of the inner cavity of the water tank body 1 to slowly be replenished into the inner cavity of the disc-shaped housing 6 through the water inlet holes 6.3.1.
